Answer86% confidence

Best overall: Anker 737 Power Bank / PowerCore 24K. It’s the strongest all-around portable charger for long flights and road trips because it has a large but airline-friendly capacity, fast USB-C charging for laptops/tablets/phones, and enough ports for multiple devices.

If you mostly charge phones, a 20,000 mAh USB-C power bank is lighter and cheaper. If you need to run a laptop heavily, choose a high-output 25,000–27,000 mAh model and confirm it is under 100 Wh for airline carry-on rules.

What could change this answer

For flights, portable chargers must go in carry-on luggage, not checked bags.
Most airlines allow power banks up to 100 Wh without special approval, but rules can vary by airline and country, so verify the Wh rating printed on the power bank before flying.
